Does divorce take place if it occurs during a period of purity in which the husband had intercourse with his wife?

The majority of scholars — and this is the issued fatwa — are of the opinion that divorce pronounced during menstruation or during a period of purity in which intercourse occurred is valid despite its prohibition. However, Sheikh al-Islam Ibn Taymiyyah held the view that such a divorce is an innovated (bid'i) divorce and does not take effect. Accordingly, the wife has become irrevocably separated from her husband with the three divorces, and there is no way for him to return to her unless she marries another man willingly, and then the new husband divorces her after consummation or dies, and her waiting period expires.
